Vari-Flo control valves feature an easy-to-use lever action handle that lets you "dial" up to seven valve/filter functions: filter, backwash, waste rinse, closed, winter or recirculate. Complete with an integral sight glass that lets you see when the backwashing cycle is completed. The wide selection of valve configurations allows you to match the right Vari-Flo valve to the proper application; residential or commercial. Comes in top-mount or side mount.
Can be plumbed on all Sand or DE Filters
